Hi!
I didn’t find the cause, probably some other script is detecting the handle change event, and the hides the whole area.
I added a preventive line of code to the ajax search pro script files via FTP you provided, the problem should be gone now.
For future reference for me, the code I used was:
[code]$(‘#range-handles-<?php echo $_in; ?>’).on(‘slide’, function(e) { e.preventDefault(); } );[/code]
